i wanted a noob for next year as a teammate. Thing I dislike in Grosjean is the conflict of interests the team boss will have. If Romain starts performing close to Kimi's level everybody will start saying how he has emerged as a team leader (remember monaco - canada period).
I dont think there's really been any evidence of a conflict of interest, I also think that Kimi performed at a level sufficiently high last season that it was a no brainer as to who the team should consider gave them their best chance of success, whether Romain can perform close to Kimi's level with any sort of consistency remains to be seen, I think he's lucky to keep his seat for next season personally.
As for what happens if did start to perform on a comparable level we'll have to wait and see, its not beyond the realms of possibility but i would say its doubtful, and in any case, if he or anyone in the team wants to proclaim Romain as team leader, i'm sure the results will show whether thats the correct title to apply, in any case, we know Kimi, he wont care what anybody calls anybody .
